2 Samuel 1:11-16

11Then David and all the men with him took hold of their clothes and tore them.

12They mourned and wept and fasted till evening for Saul and his son Jonathan, and for the army of the Lord and for the nation of Israel, because they had fallen by the sword.

13David said to the young man who brought him the report, “Where are you from?” “I am the son of a foreigner, an Amalekite,” he answered.

14David asked him, “Why weren’t you afraid to lift your hand to destroy the Lord’s anointed?”

15Then David called one of his men and said, “Go, strike him down!” So he struck him down, and he died.

16For David had said to him, “Your blood be on your own head. Your own mouth testified against you when you said, ‘I killed the Lord’s anointed.’ ”
